CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. patent application Ser. No. 16/019,738, filed on Jun. 27, 2018 and titled “Multi-Anchoring Depth Control System,” which is a continuation of U.S. patent application Ser. No. 15/414,087, filed on Jan. 24, 2017 and titled “Multi-Anchoring Depth Control System,” now issued as U.S. Pat. No. 10,035,566, which claims the benefit of U.S. Provisional Patent Application No. 62/407,245, filed on Oct. 12, 2016 and titled “Dual Anchoring Depth Control System,” the entire contents of which are incorporated herein by reference in their entirety.

BACKGROUND OF THE INVENTION

Boat anchoring systems are generally known. Existing boat anchors are generally single anchors which must be manually set to a desired depth. As tides and other water conditions change or a storm approaches, traditional boat anchors must be monitored and adjusted to ensure the correct amount of anchor line is let out and to retain the boat in a desired location or at a desired depth. Such adjustments require relatively constant attention to a boat. A need therefore exists for an anchoring system which can be programmed to maintain the boat and anchor in a desired location or at a desired depth and automatically adjust the length of the anchor line accordingly.

Referring to FIGS. 1 and 2, wherein like numerals indicate like elements throughout, a first preferred embodiment of a multi anchoring depth control system 10 is shown, including a boat 12. The first preferred embodiment of the depth control system 10 preferably includes two anchors 20 connected to the boat 12 by a single line or cable 22, wherein the dashed line represents a portion of the line 22 preferably running within the boat 12. In the first preferred embodiment, one of the anchors 20 extends from the bow 14 of the boat 12 and another anchor 20 extends from the stern 15 of the boat 12. Each anchor 20 and the line 22 are preferably controlled by a motor 30 capable of raising or lowering the anchors 20 by releasing or retracting the line 22.

The first preferred embodiment of the depth control system 10 can include a single motor 30 which the line 22. The depth control system 10 also preferably includes a depth finder 40 mounted in the boat 12 to determine the depth D of the water beneath the boat 12 from the water surface 42 to the floor 44 of the ocean, lake, river, or sea. The depth finder 40 can be a commercially available product such as those manufactured by GARMIN (GARMIN is a registered trade mark to Garmin Switzerland GmbH), HUMMINBIRD (HUMMINBIRD is a registered trade mark to Johnson Outdoors Marine Electronics, Inc.), and the like. The depth finder 40 preferably conducts measurements by SONAR, but is not so limited. The depth control system 10 preferably includes a light source 80 and a speaker 90 that are preferably configured to light or emit a sound when the length of the line 22 is automatically adjusted, as described below.

Referring to FIG. 2, the depth control system 10 preferably further includes a computerized controller 60 for managing the system 10. The controller 60 preferably includes keys or buttons 62 and/or a screen 64. The screen 64 is preferably touch-sensitive. The controller 60 constantly or at predetermined and optionally customizable intervals monitors the depth of the anchors 20 and of the water under the boat 12 in connection with the depth finder 40. The depth control system 10 preferably further includes a sensor 65 capable of measuring the angles θ and θ′ of the lines 22 in relation to a vertical plane V. The sensor 65 is preferably also capable of detecting the tension or vibration of the lines 22. In an alternate embodiment, the controller 60 is capable of calculating the angle θ based upon the depth D measured by the depth finder 40 and the length L of line 22 that has been released by the motor 30 based upon the formula cos(θ)=D/L. The depth control system 10 further includes a GPS receiver 70 in communication with the controller 60. The controller 60 preferably includes a wireless receiver 66 for remote communication with the controller 60, such as by cellular data network in communication with a user's cellular phone, tablet device, or a dedicated remote controller 75, which can further include a screen 76 and/or buttons 77. The cellular phone, tablet device, or dedicated remote controller 75 are preferably configured to transmit a set of GPS coordinates to the controller 60.

Referring to FIG. 3, a second preferred embodiment of the multi anchoring depth control system 110 is shown. The second preferred embodiment includes a boat 12 and at least two anchors 20. The anchors 20 are each connected to the boat 12 by their own dedicated line or cable 122. Each anchor 20 and cable 122 pairing is preferably controlled by its own dedicated motor 130 capable of raising or lowering the anchors 20 by releasing or retracting each line 122 independently of the amount of line 122 released or retracted by any other motor 130. The second preferred embodiment of the depth control system 110 preferably also includes a depth finder 40 and is preferably paired with the controller 60 shown in FIG. 2 and described above.

Referring to FIG. 4, a third preferred embodiment of the multi anchoring depth control system 210 is shown. The third preferred embodiment includes a boat 12, an anchor 20, and a fastener 220. The anchor 20 and fastener 220 are each connected to the boat 12 by their own dedicated line or cable 222. As shown, the fastener 220 is connected to a fixed object in the water, such as a piling, dock, buoy, moor, or the like, indicated as 221. Each line 22 is preferably controlled by a dedicated motor 230 capable of releasing or retracting the amount of line 222 needed to maintain the boat 12 at a consistent depth and/or distance from the piling 221, in the manner described above. The depth control system 210 may also include a radar detector 270 for us in measuring the distance between the boat 12 and the piling 221. The third preferred embodiment of the depth control system 210 preferably also includes a depth finder 40 and is preferably paired with the controller 60 shown in FIG. 2 and described above. The depth control system 210 is not limited to the one-anchor 20 and one-fastener 220 configuration as shown, but may be configured to include two or more fasteners 220 for use with or without one or more anchors 20.

In use, a user can program the controller 60 to maintain the boat 12 at a desired depth, such as in twelve (12) feet of water, either through the buttons 62, the preferably touch-sensitive screen 64, or through his or her cellular phone, tablet, or remote controller 75. Alternately, the user can program the controller 60 to retain the boat 12 at a specific location using the GPS receiver 70. Upon the selection of a desired depth or location, if the boat 12 is not already located at the desired location or depth, the controller 60 commands the motor 30 to retract the line 22 or lines 122 to lift the anchors 20 from the floor 44 of the body of water. The controller 60 then commands the engines (not shown) of the boat 12 to adjust the position of the boat 12 so that it is relocated to the desired location. Upon reaching the desired location, or if the boat 12 was already at the desired location or depth, the controller 60 communicated with the depth finder 40 to determine the depth of the water and commands the motor 30 to release an appropriate amount of line 22 or lines 122 to place the anchors 20 on the floor 44 of the body of water to hold the boat 12 in place. While the anchors are released, the depth finder 40 continually or periodically, such as once per second or once per minute, measures the depth of the water and communicates that information to the controller 60. Upon receiving the depth of the water from the depth finder 40, if the controller 60 determines that an adjustment to the length of line 22 or lines 122 is necessary, the controller 60 causes the light source 80 and/or speaker 90 to emit a light and/or sound to alert those nearby the boat 12 that an automatic adjustment will soon take place. The emitted light or sound can be any type suitable to alert those around the boat 12 that it will be moving, such as a solid or blinking light or a buzzing or beeping sound. The light source 80 can alternately be configured to illuminate all or part of the area around the boat 12 before an automatic adjustment takes place, preferably in conjunction with a light detecting sensor (not shown) configured to adjust the brightness of the light source 80 based upon the amount of ambient light. The controller 60 further sends a communication signal to the cellular phone, tablet, or remote controller 75 containing a notification to the user that the automatic adjustment of the boat 12 will soon begin. The controller 60 then recalculates the appropriate amount of line 22 or lines 122 that is/are released and commands the motor 30 or motors 130 to release or retract more line 22 or lines 122 as necessary to maintain the boat 12 at a correct depth or location.

If the depth finder 40 is configured to monitor the water depth continually or with enough frequency, the controller 60 is configured to calculate the depth of passing waves based upon short-term fluctuations in the depth as measured by the depth finder 40. When the depth of passing waves reaches a sufficiently high level, the controller 60 preferably automatically adjusts the amount of line 22 or lines 122 that is/are released to properly account for storm conditions with larger waves, thereby automatically retaining the boat 12 at a safe depth and location without additional intervention by a user. When the user wishes to move the boat 12, he or she can instruct the controller 60 to retract the anchors 20.

Another example of the use of the depth control system 10, 110, 210 is shown in FIG. 5. At step 510, the user uses his or her cellular phone, tablet device, or dedicated remote controller 75 to send a desired location for the boat 12 to the controller 60 as a set of GPS coordinates. At step 520, the controller 60 communicates with the sensor 65 to determine whether the anchors 20 are extended and, if so, commands the motors 30 to retract the anchors 20. Next, at step 530, the controller 60 commands the motors (not shown) of the boat 12 to adjust the position of the boat 12 so that the boat 12 is moved to the GPS coordinates designated by the user. At step 540, the controller 60 communicates with the depth finder 40 to determine the depth of the water. At step 550, the controller 60 uses the depth determined by the depth finder 40 to command the motors 30 to release the correct amount of line 22 to place each anchor 20 on the floor 44 of the body of water. After the anchors 20 reach the floor 44, at step 560, the controller 60 communicates with the depth finder 40 to measure the depth of the water. At step 570, the controller 60 calculates whether the depth of the water has changed since the previous measurement, and if so, releases or retracts the appropriate amount of line 22 to maintain the boat 12 in place and the anchors 20 on the floor 44 as the depth changes.
